Dick Faurot's Weather Blog: Cool Weekend; Frost Likely Sunday Morning

Suggest protecting any tender plants, particularly for the Saturday night time frame as that is when frost and, perhaps, even a freeze will be most likely.

The cooler, drier air that moved in behind last night’s cool front has made quite a difference for us today; notice the 24-hour temperature change map, for example, and also the max/min temperature map for today, courtesy of the OK Mesonet.

There could be some patchy frost tonight as well due to clear skies and light winds, which will allow temperatures to drop off into the upper 30s to near 40. The normally cooler valleys in NE OK will be the most likely locations for a frosty start. Bright, sunny skies through the day and a light NE wind will make for a pleasant, cool autumn day with temperatures reaching the low-mid 60s during the afternoon hours.

Sunday morning still looks to be the coldest of the season for us so far, with low-mid 30s for most locations and the potential for a light freeze, particularly in the colder valleys of NE OK.

For the Tulsa metro area, the urban environment should keep temperatures from officially reaching the freezing mark, but frost looks to be a good bet.

Bright, sunny skies that afternoon, along with daytime highs in the lower 60s and a light easterly breeze, will make for another very pleasant autumn afternoon.

Gusty southerly winds will return early next week, resulting in much warmer temperatures, particularly at night, as you can see on our forecast page. Clouds will also return, but no mention of rain is currently anticipated until Wednesday, which is also when our next cool front will be arriving.

As you can see on the 7-day QPF, this does not look to be a particularly wet system for us, with the heavier amounts now anticipated to be further east and south, but, that is certainly subject to change in the days ahead. At any rate, showers, and potentially a few storms, on Wednesday will be followed by another cool down going into the latter part of the week.

Although we are getting later into the month of November, this next cool-down is still not looking to be all that cold, and no real cold air is yet in our forecast. The longer range guidance continues to suggest temperatures will average above normal as we look at the 8-14 day outlooks, for example.

So, although some frosty mornings appear likely, our first widespread freeze still looks to be beyond this forecast time frame.

A few showers and storms have developed overnight and will quickly exit the area early this morning. Red Flag warning criteria will be met today across a large portion of northeastern Oklahoma to the west.
